i want to create a light that cycles through all colours in the rgb range, how would i do so?
Select HSL color mode for interpolation.
Choose Clockwise method.
Select pure red color - R: 1, G: 0, B: 0.
Select pure red color and add a bit of blue - R: 1, G: 0, B: 0.01.
Animate Factor - press I over it to put keyframe on selected time frame.
